• Chord Speeds of Sound Bar Graph - a visual comparison between the calculated
speeds of sound for each chord.
• Gain/Performance Bar Graph - provides either a visual comparison of the average of
the upstream and downstream gains for each chord or a visual comparison of the
average of the upstream and downstream performance for each chord.
• Signal to Noise Bar Graph - provides a visual comparison between the signal to noise
ratio for each chord direction.
• Meter Status Alarms - provides a visual indication of the meter’s status.
• Gas Comp - this dialog shows the gas composition that can be used by the AGA8 or
AGA10 gas calculations.
• Baseline - this dialog shows the meter’s flow characteristics in comparison to limits
defined for the Continuous Flow Analysis features. This dialog is only available for
four path meters that support a baseline and a valid Continuous Flow Analysis key.
• Run time - displays how long the monitor screen has been collecting data.
• Meter Time - the time displayed is the time from the Ultrasonic meter.
Note
If the time displayed has a yellow background, that is an indication that the meter’s time is
more than 10 minutes apart from the PC’s time.
• Meter Data List - displays read-only data selected from the drop-down list.
• Chart - the chart utility displays the data collected for the value selected from the
Chart drop-down list.
Refer to Table 2-1 for error resolutions and Table 2-2 for meter maintenance hardware
diagnostics.

Daniel MeterLink utility Diagnostics Action(s)
Meter Monitor (Summary) view • Check Status for active
alarms
• Meter Status LED is green if
there are no active alarms.
This indicates the meter is
measuring flow and operat-
ing within the calibrated
parameters.
• Meter Status LED is red.
This indicates an active
alarm. Resolve and ac-
knowledge active alarms as
displayed on the Status
Summary page. Click the
Help button beside the
